Permanent Establishment in Indonesia: BUT Rules and Tax

Recognise BUT as a tax-nexus question

A BUT (Bentuk Usaha Tetap), often translated as permanent establishment, is a tax nexus question created by the way a foreign person or foreign company conducts business or activities in Indonesia. It is not a voluntary label that can be avoided by calling a team a liaison office or by leaving the foreign parent as the contract party. The official DJP Regulation PMK 35/PMK.03/2019 on determining a BUT explains the detailed determination framework and treats a BUT as a form of business used by a foreign individual or foreign entity to carry on business or activities in Indonesia.

The first practical consequence is tax registration. The official PMK text says a foreign individual or foreign entity carrying on business or activities through a BUT must register to obtain NPWP, and it sets a timing rule linked to the start of those activities. It also addresses VAT registration for a BUT making taxable supplies. Do not wait for a corporate-law incorporation event before testing the tax facts: a BUT can arise from the operational footprint itself.

A BUT is not the same as a PT PMA, a branch registration, or a representative-office approval. Those are entity or licensing questions. The BUT review asks whether the facts create an Indonesian taxable presence, what income and obligations follow, and how domestic rules interact with any applicable tax treaty.

Map the presence facts before concluding

Build the review from evidence, not labels. Collect office leases, access records, equipment or warehouse use, personnel contracts, time sheets, work orders, project schedules, customer contracts, purchase orders, powers of attorney, sales approvals, payment flows, IT architecture, data on Indonesian users, and correspondence showing who actually performs or concludes the key business activity. A short fact map is more useful than a vague statement that the company has ‘no office’ in Indonesia.

The PMK determination framework contains categories that include a place of management, branch, office, factory, workshop, project and other physical or activity-based manifestations. It also contains agency and electronic-transaction concepts. Do not try to decide a category from one fact alone. The right analysis considers the nature, continuity, authority, commercial function, and relationship of the Indonesian activity to the foreign enterprise’s income.

Create a dated evidence record

• Place: exact locations, lease or use rights, access, signage, assets, personnel attendance, and the period each site is available to the foreign enterprise.
• People: employee, director, contractor, or agent roles; authority to negotiate or conclude contracts; sales or delivery functions; and supervision or reporting lines.
• Projects: contract scope, site, start and end dates, milestones, subcontractors, variations, mobilisation, and the entity carrying operational responsibility.
• Digital: system operator, local users, payment and fulfilment flows, local agent arrangements, technology deployment, and the metrics relevant to the current law.

Keep the record updated. A short project can become an ongoing operating presence; a marketing agent can take on contract authority; and a platform can add payment or fulfilment functions. The factual story must be reassessed when the operating model changes.

Use a treaty-plus-domestic-law comparison

Start with Indonesian domestic law and the current administrative rules, then determine whether an applicable tax treaty affects the result. A treaty can contain its own permanent-establishment definition, conditions, exclusions, duration tests, or agency rules. Treaty benefits are not assumed from a parent company’s country name; residence, entitlement, documentation, and the specific treaty article must be checked. Use the current {treaty} together with the actual treaty text and relevant guidance.

Prepare a comparison sheet that lists each material fact on the left, the domestic-law relevance in the middle, and the treaty question on the right. Include the source and date for every conclusion. This approach makes it easier to identify the points that need specialist confirmation: whether the place is at the enterprise’s disposal, whether a project duration test is met, whether an agent is independent, whether activity is preparatory or auxiliary, or whether the digital rules apply to the current facts.

This is an assessment discipline, not an election. If the conclusion is uncertain, preserve the facts and obtain current specialist advice before the business adds new contractual authority, staff, facilities, or revenue-generating Indonesian functions.

Registration, NPWP, VAT, and bookkeeping controls

Where a BUT is established, its tax obligations need an implementation plan. The PMK determination page directly addresses NPWP registration and the situation in which a BUT making taxable supplies is required to be confirmed as a taxable entrepreneur under the VAT system. Verify the current procedure, timing, filing profile, invoice requirements, withholding position, and record-keeping obligations with the Directorate General of Taxes ; do not extrapolate a tax checklist from a different entity type.

Build an obligation calendar with the exact taxpayer identity, effective date, tax office or portal status, recurring returns, payment dates, invoice owner, bookkeeping location, responsible signatories, document retention, and treaty documentation. Reconcile it to the commercial system. If the tax registration says one thing while contracts, invoices, payroll, or revenue allocation say another, resolve the inconsistency before a filing or audit does it for you.

For a related but distinct overview of tax-ID registration after an Indonesian company is formed, see the NPWP guide for Indonesian companies . It should not be used as a shortcut for a foreign enterprise’s BUT analysis; the taxpayer facts and implementation route can be different.

Avoid mixing tax existence with entity licensing

A tax conclusion does not by itself authorise a business activity, and a licensing document does not by itself settle tax nexus. Keep the two workstreams connected but distinct. The tax workstream maps the foreign enterprise’s presence and compliance. The entity and licensing workstream asks whether an Indonesian company, representative office, project entity, sector permission, or other formal route is required for the way the business will operate.

If the commercial plan needs an Indonesian entity to contract, invoice, employ an ongoing team, own assets, or obtain operational permissions, check company registration in Indonesia separately. The live OSS risk-based licensing system system is a reference for risk-based licensing, but it does not turn a tax-only conclusion into a complete market-entry plan.

Review both workstreams whenever the foreign enterprise opens a site, hires or relocates personnel, appoints an agent, begins a construction or installation project, adds Indonesian payment or fulfilment infrastructure, or changes contractual authority. The best control is a shared change log that forces tax and licensing owners to re-test the facts at the same time.
